To all whom it may concern: I 1 Be it lmo wnthaitfI, GEORGE Q'num, a that Zen of theUhiteii States, residing at Ghicage, in the county df Cock and "State cf Illinois, have invented t new seful Improvemefit in Devices for Smocthing 0'1 Dreesing Rails, of which the ioilowil g is'a speci ficetion; i x

This invention relates I tc imprcvemerits in devices for smoothing or dressing rails; ishere shown as em'bcciid in a deyice'partice lariy :yppliczihle for use in co'pnectich with sl rloothingcr dl es sing rails such as are used, for GXELIIIPIB, for carrying traveling cranes, orehridges, and similar heavy leadmg and uploaflih'g devices 011 ether machinery oreppar'etus supported on carpi-ages opeiztting on rails.

The rails used in connection with such devices which usually are quite heavy, frequently qiiick1ydeve l0p beadgfins or' pro trudiiig etiges'etthema'lgins of their uijper surfaces as a tesult "of the load-s cerried by them. For various reasons it frequently desiiable or necessary that the rails be smoothed'er dressed "by remti'ving these heads, fins feather edges, or protruding ed es therefrom. l

the use Of my inventien, the rails may be smcdthed or "dressed without retrieving them from their position inthe track, that is, in situ. By the use of my i'plventib'h, ellsc the W915i; my be easily and cheap ly done; and the device for aconipl'ishingthe same may he quickly andchez ply lmide and is sim 1c in cperatiqh and 'diirdble. T h'e device is alaptedfor, attachment to the carriage of the traveling crane',"er bridge of ether a ppa ratus running 0T1 the rails to be smoothed; and is ,edthted to operate on meme a e ew F esm e eq- 18, 192;, serial NQ. 156,693,

Since the cross head 17 iis'pfiv otitl'ly mounted on the phi 13, it will be seen thetlby adjusting the set sc ews and 21,

the member 12 may be ed lewered. The member 12, which n y ng bri e h'ei e f h r i d p d t remove he fea he e ge to b 161 fycm each margin ogtthe u jperfsurfaceg Figfl2 these heads as the genie ape cut 01f by the tools 22 and 23, are indicated by 24, 24;. The cutting tools 22 and 23 are adjusted by means of the screws 25 and 26,131 spectively, and are adapted to be firmly clamped in any osition by n e'ens of the clogs 27 and 28, respectively which are hleld by heans of the nlits and 30, respectively. The 0001 holder isheld in its 'p 'cper rela tier; to the 'si-dfes'icf the rail theppposed gu'ide screws 31 tpndf32. Theinner ehd cf each o'f'these guide screws is previded with a ba11bearing Where it c ontacts with the 1% O tl a l- 7 26 1" ea i g 01 cl i$ ihdiceted 33 it ii; to uh'giei'istootlthat guide screw 32has similar 1 9511 cbntactihg with the other sic le of the m1 t i dmw "rod 34 is also which it'sf fpiwaifd end ettecheghtc k'et35 fe stenedflte the m mber 11. The aif egjd dfthe draw rea ems bifii reated as indie ed b 3'6; the five tide of theilbifi i'caited p rt being pivetaili secured tt-the mee epin m n n c eel; the We 12: 35W? i 'i i In operation, the device is secured to the frame 11 by means of the brackets 14 and 35 as shown, and the cutters 22 and 23 and. the guide screws 31 and 32 are adjusted so that the proper depth of cut will be made to take off any bead or feather edge on the sides of the upper surface of the rail 10. The height of the cutting tools is adjusted by means of the screws 20 and 21. The pivotal mounting of the tool holder 12 on the pivot pin 13 is provided because of the usual side play present in the movement of the cranes or bridges on the rails. The flanged wheels supporting the bridge or crane on the rails frequently permit up to a couple of inches of side play in their movement. Such side play does not affect the operation of the cutting device because the guide screws 31 and 32 will keep the cutting tools in the proper position and the necessary relative sideways motion with respect to the member 11 isrpermitted by means of the pivot 13. The draw rod 34 has suiiicient lost motion where it is attached to the bracket 35, or is sufficiently flexible, or both, to permit the necessary pivoting on the pivot 13.

The draw rod 34 exerts a pull on the tool carrier 12 near its lower end and thus removes the strain that otherwise would be put on the pivot 13 during the cutting operation.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the append ed claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.
